Try --label/--test-label:

1. Creating archive:

$ tar -czvf test.tar.gz --label="`cat description.txt`" mydir

2. Testing the rchive:

$ tar -tf test.tar.gz
This tar is created for test purpose.
[..archive listing follows..]

3. Viewing the label:

$ tar --test-label -f test.tar.gz
This tar is created for test purpose.

4. Checking whether the label matches given text:

if tar --test-label \
   -f test.tar.gz 'This tar is created for test purpose.'; then
   ...
fi

The --test-label option appeared in tar 1.24. You will get more info
on it in the GNU tar Manual, section 9.7 "Including a Label in the
Archive" (an online copy is available at
http://www.gnu.org/software/tar/manual).

Hope that helps.
